build_instance.sh is producing image names directly based on registry name (i.e. registry.gitlab.syncad.com/hive/clive:<tag>)
Also it performs local image tagging as `instance` and `minimal-instance` to satisfy build_and_publish_intance.sh script.

This script will set beekeeper to be used with CLIVE_BEEKEEPER_SESSION_TOKEN. This script will also intercept signals, so that beekeeper instance will be closed gently, without leaving locks on wallet.

No need to exclude "test_tools.__private.logger" anymore in check_is_private_key_nor_password_is_not_logged script

Because test-tools now have a different logger and this text is not
logged out anymore in every line

Improve result messages in check_is_private_key_nor_password_is_not_logged and check_for_dangling_beekeeper scripts

Because as can be observed there:
https://gitlab.syncad.com/hive/clive/-/jobs/1260490#L88

test-tools seems to log all envrionment variables which also include
CI_COMMIT_MESSAGE during CI and when e.g "password" text is used in
the commit name, there will be a false positive.

Due to latest changes in hived docker images:
- git was removed, so we no longer require it in dockerfile
  (previously it was required for poetry install and
  poetry dynamic-versioning commands. It was fixed by
  embedded_testnet_instance installing only dev packages
  via the --no-root switch, so it requires already installed clive
  from previous stage)
- need to install libboost-all-dev because wax requires it
- need to install poetry just for the embedded_testnet_instance
  (so we can supplement with dev dependencies only. We also create venv
  by python3-venv instead of poetry now)
